Application filed May 28, 1912. Serial No. 700,342.

To all whom it may concern:

Beit known that L'OSOAR OARLsoN, a c1tizen of the United States, residing at "Weedville, in the county of Elk and State of Pennsylvania, have invented certain new and useful Improvements in Gang-Flows, of whichthe following is a specification.

This invention relates to gang plows and consists in certain novel features of construction and arrangement which are illustrated in the accompanying drawings and will be hereinafter first fully described and then more particularly pointed out in the claims.

For a full understanding of the invention, reference is to be had to the following description and accompanying drawings in which:

Figure l is a top plan view of the plow; Fig. 2 is a side elevation of the same; Fig. 3 is a side elevation of the same viewing the plow from theopposite side from that shown in Fig. 2; Fig. 4 is a longitudinal sectional view of the plow; Fig. 5 is a rear elevation of the same; Fig. 6 is a front elevation of the same.

This plow includes a frame 1 which is supported at its forward end upon a shaft 2 which is slidably mounted in a block 3 carried at the forward part of the frame 1. A furrow wheel 4 is journaled for rotation at the lower end of the shaft 2, and the said furrow wheel 1s pitched at an angle to a vertical plane in the usual manner. A collar 5 is adjustably mounted upon the shaft 2 and is received between the lugs 6 of a block 7. A lever 8 is fulcrumed upon the block 3 and a link 9 is pivotally connected at one end with the block 7 and at its other end with the lever 8. A spring pawl 10 is carried by the lever 8 and is adapted to engage the teeth of a gear segment 11.

It is apparent that by swinging the lever 8 the forward end of the frame 1 will be raised or lowered along the shaft 2, and when the forward part of the frame 1 is at a desired elevation the partsmay be maintained in this position by permitting the pawl 10 to engage the teeth of the segment 11. An arm 12 is fixed to the upper end of the shaft 2 and carries a spring pressed pawl 13. A casting 14 is pivoted at the upper end of the shaft 2 above the arm 12 and is provided with teeth 15 which are adapted to be engaged by the pawl 13,

with a laterally disposed whereby the casting 14 is held at an adjusted position with relation to the arm 12. A bracket 16 is pivoted to the casting 14, and a guiding tongue 17 is fixed to the bracket. A shaft 18 is journaled at the rear part of the frame 1 and is provided at its upper end arm 19.

A rod 20 is pivotally connected at its forward end with the casting 14 and at its rear end with the arm 19. Thereforeas the shaft 2 is turned the rod 20 moves longitudinally and through the arm 19 the shaft 18 is turned. A furrow upon the lower end of the shaft 18 and is pitched at an angle to a vertical plane in the usual manner. The furrow wheels 4 and 21 are connected in such manner that when the forward furrow wheel turns in one direction the rear furrow" wheel turns in the opposite direction, and vice versa.

A shaft 22 is mounted upon the frame 1. An arm 23 is mounted at the outer end of the shaft 22 and carries a shaft 24 which in turn carries a ground wheel 25. A lever 26 is fulcrumed upon the shaft 22 and is provided with a spring-pressed pawl 27 which is adapted to engage the teeth of a gear segment 28 mounted upon the frame 1. The lever 26 is provided at its side with a lug 29, and a lug 30 is provided upon the arm 23.

A rod 31 passes through the lugs 29 and 30, and a coil spring 32 surrounds the rod and bears at its ends against the lugs 29 and 30. By this arrangement the axis of the shaft 24 may be swung about the aXis of the shaft 22, and thus the side portionpf the frame 1 may be raised or lowered, and when at a desired elevation the parts may be retained in such relation by permitting the pawl 27 to engage the teeth of the segment 28.

A hub 33 is journaled upon the shaft 22 and is provided with sets of sprocket teeth 34 and 35. A sprocket wheel 36 is fixed to the inner end of the shaft 24 and a sprocket chain 37 is trained around the sprocket wheel 36 and the set of sprocket teeth 34. The said sprocket chain is adapted to transmit rotary movement from the shaft 24 to the hub 33 upon the shaft 22. An operators seat 38 is mounted upon the frame 1. A crank shaft 39 is journaled upon the frame 1 in the vicinity of the forward end thereof, and a crank shaft 40 is journaled upon the intermediate portion of the frame 1. A

wheel 21 is journaled' positions they rest lever 41 is fixed to the crank shaft 40 and is provided with a spring pawl 42 which is adapted to engage the notches of a segment 43 mounted upon the frame 1, whereby the crank of the shaft 40 may be held at a desired position with relation to the axis of the shaft.

. Plow beams 44 are pivotally connected with the cranks of the shafts 39 and 40. These beams are connected together at their forward ends in the clevis 45 is pivotally mounted at the forward end of the beams. A bar 46 is fixed between the forward end portions of the beams 44 and is provided with a series of perforations 47. A pin 48 is adapted to be passed through the bar 46 and any one of the perforations 47, whereby the clevis may be supported at a desired angle at the forward end of the beams.

Bars 49 depend from the forward part of the frame 1 and carry at their lower ends a cross bar 50, the end portions of which lie below the lower edges of the beams 44, and when the said beams are at their lowermost upon the end portions of the bar 50. Brackets 51 are attached to the beams 44 and carry at their lower ends colter wheels 52. Plow bodies 53 are carried at the rear ends of the beams 44. A shaft 54 is journaled for rotation at the rear portions of the beams 44 and carries at one end blades 55 which are located just behind the mold board of the foremost plow body 53. An arm 56 is secured to one of the beams 44 and is slotted at its outer end and receives the shaft 54. A sprocket wheel 57 is fixed to the end of the shaft 54, and a sprocket chain 58 is trained around the set of sprocket teeth 35 and the sprocket wheel 57 An escapement device is mounted upon the hub of the sprocket wheel 57 and is so arranged that when the wheel 57 is rotated rotary movement is transmitted to the shaft 54, but the shaft 54 may be rotated without rotating the wheel 57.

A lever 60 is pivoted in brackets 61, which in turn are connected to the beams 44. This lever is provided with arms 62 in which the shaft 54 is j ournaled. The lever is provided with a spring-pressed pawl 63 which is adapted to engage the teeth of a segment 64 mounted upon the adjacent plow beam 44. Therefore it will be seen that when the lever 60 is swung the arms 62 will raise or lower the shaft 54 with relation to the plow body. A shaft 65 is journaled behind the rear plow body and is provided with arms 66 in which is journaled a shaft 67. The shaft 65 is provided with an upstanding arm 68, and a rod 69 is pivotally connected with said arm and is also pivotally connected with the lever 60. The shaft 67 carries a set of blades 70, and these blades are arranged to operate upon the furrow slice which is turned usual manner, and a:

by the rear plow body. It will be seen that when the lever 60 is swung both of the sets of blades are adjusted with relation to their respective plow bodies. A sprocket wheel 71 is fixed to the shaft 54, and a sprocket wheel 72 is fixed to the shaft65. A sprocket chain 73 is trained around the wheels 71 and 72 and is adapted to transmit rotary'movement from the shaft 54 to the shaft 67. A two-armed treadle 74 is pivoted at the inner end of the shaft 22 and is connected by means of a link 75 to the side of one of the beams 44. Oppositely disposed springs 76 and 77 are connected with the treadle 74 and are alsoconnected with the frame 1. These springs are under tension with a tendency to normally hold the beams 44 and their attached parts in elevated positions. When it is desired to lower the beams, an operator presses his foot upon the forward arm of the treadle 74 and at the same time swings the lever 41 and when it is desired to raise the beams, the lever 41 is swung in the opposite direction and pres sure is exerted by the foot upon the rear arm of the treadle. Slack absorbers 7 8 bear against the upper and lower runs of the chain which passes around the gear teeth 35, and the said absorbers serve to hold the runs of the chain sufficiently tight to efiectually operate the parts.

It will be seen that a gang plow is provided in which the forward and intermediate portions of the frame may be adjusted vertically and that the beams may be adjusted vertically with relation to the frame, and that the soil pulverizers located behind the plow bodies may be adjusted with relation to the plow bodies. At the same time the furrow wheels are operatively connected together to be turned simultaneously in opposite directions as the guiding tongue is swung. Therefore the plow can be turned promptly in passing around the field.
